Answer:Mostly in Africa but can also be found in Asia, Europe, and Antarctica.
Explanation:
Biogeographic isolation : Isolation through distribution of Species in geographic space and time
so , one of the answer is The isolation of two populations of the same species
By doing this, decrease the chance of any cross breeds between species, which eventually will led to Speciation
Highe clouds have added moisture to. lower cloud, which cannot hold its droplets anymore
The statement that BEST describes the relationship between concentration and enzyme activity is when substrate concentration decreases, enzyme activity decreases (Option B).
- Enzymes are proteins that speed up chemical reactions by lowering the activation energy of that reaction.
- Some factors that alter enzymatic activity include temperature, pH, and substrate concentration.
- An enzyme works in optimum condition as long as there is more substrate available which can be broken down by the specific enzyme.
- However, the enzymatic activity increases as the substrate concentration until a limiting value is reached.
In conclusion, the statement that BEST describes the relationship between concentration and enzyme activity is when substrate concentration decreases, enzyme activity decreases (Option B is correct).
